Introduction: Twenty years ago, the results of Endophthalmitis Vitrectomy Study (EVS) were adapted worldwide as the standard management of endophthalmitis. The study suggested that there was no benefit of performing vitrectomy for acute postoperative endophthalmitis, unless for patients who presents with visual acuity of light perception. However, vitrectomy with advanced technology and technique has been changed rapidly in the last decades; therefore, we need to reconsider its role. We conducted a study and the purpose of our study was to describe the indications for vitrectomy and the outcomes in acute postoperative endophthalmitis at Cipto Mangunkusumo Hospital, Jakarta, Indonesia. Methods: Our study was a descriptive-retrospective case series. We reviewed clinical and microbiological records of all patients with clinical diagnosis of acute postoperative endophthalmitis who underwent vitrectomy in Cipto Mangunkusumo Hospital between 2007 and September 2015.  Presenting visual acuity, visual outcome and complications were described. Result: Our study was a descriptive-retrospective case series. We reviewed clinical and microbiological records of all patients with clinical diagnosis of acute postoperative endophthalmitis who underwent vitrectomy in Cipto Mangunkusumo Hospital between 2007 and September 2015.  Presenting visual acuity, visual outcome and complications were described. Conclusion: An eight-year experience has taught us that vitrectomy offers better treatment outcome in the group with visual acuity of hand movement than those who only had visual acuity of light perception.

Purpose : The aim of this study is to report a case of intraorbital wooden foreign body with intracranial extension to the frontal lobe and its management. Method : This is a descriptive study: A 53 year-old male referred due to wooden stick stucked in the orbital cavity causing protruding eyeball and vital sign instability. Result : Right eye examination revealed light perception visual acuity, with bad light projection and bad color perception, inwardly folded upper eyelid, proptosis, conjunctival chemosis, corneal erosion and edema, dilated pupil with sluggish pupillary light reflex and limited ocular movement in all direction. Vital sign was unstable with decreasing blood pressure, increasing temperature and heart rate. CT Scan showed complete fracture of the orbital roof due to penetration of the wooden stick, pneumoencephalus, cerebral edema and hematoma. Emergency craniotomy was performed to remove the penetrating wooden stick and bone segment in the frontal lobe and fracture repair. Ophthalmologist pulled the remaining stick, released the superior rectus muscle and repaired the lacerated eyelid. Outcome visual acuity was no light perception with lagophthalmos and limited ocular motility. Patient was admitted to Intensive Care Unit one day post-operatively and treated with systemic and topical antibiotic. Conclusion : Any case presenting with intraorbital foreign body must undergo immediate neuroimaging to exclude any intracranial extension, especially in patients with worsening general condition.

We present the management and postoperative course of a persistent fetal vasculature (PFV) case. A four-year-old girl visited the Eye Department of Hippokration, General Hospital of Thessaloniki due to reduced visual acuity of her left eye. She was diagnosed with PFV and underwent surgery (lensectomy, capsulorhexis of the posterior capsule, insertion of an intraocular lens in the posterior chamber, and posterior vitrectomy) in order to dissect the PFV. Along with the postoperative medical care, she underwent intensive treatment for amblyopia. The postoperative course was uncomplicated, and the visual acuity of her left eye improved from hand movement to 20/25 with proper correction. Patients with unilateral PFV and gradually deteriorating visual acuity could be good candidates for a combined surgical procedure, as the one described above, with a good prognosis.

Abstract Background Patients presenting with macula-off rhegmatogenous retinal detachment (RRD) with concomitant age-related macular degeneration (AMD) and their treating physicians would benefit from knowledge regarding the visual prognosis after repair. The prognosis for such patients is not well known. The purpose of this study is to compare visual outcomes in macula-off RRD in eyes with AMD versus a group of comparison eyes without AMD. Methods This was a retrospective chart review of 1,149 patients. A total of 191 eyes met study criteria, 162 non-AMD eyes (controls) and 29 AMD eyes. The main outcome measure was postoperative visual acuity in control eyes versus AMD eyes, and this was compared using Fisher’s exact test. Results There was a statistically significant difference in postoperative visual acuity by AMD status, with those without AMD having a higher frequency of Count Fingers (CF), Hand Motion (HM), Light Perception (LP), or No Light Perception (NLP) vision (p = 0.023). More specifically 5.56% of non-AMD eyes and 3.45% of AMD eyes were 20/40 or better, 77.16% of non-AMD and 55.17% of AMD eyes were worse than 20/40 and better than 20/200, 10.49% of non-AMD eyes and 37.93% of AMD eyes were 20/200 or worse, and there were 11 eyes in the non-AMD group with CF, HM, LP, or NLP vision while there was only 1 eye in the AMD group with CF vision. Conclusions Though postoperative visual acuity was worse in the non-AMD group with a higher frequency of patients having final vision of CF, HM, LP, or NLP, this is not likely a clinically significant finding. Rather, it is a function of the difference in sample size and composition between the two groups. Importantly, this study suggests AMD patients can expect similar outcomes to non-AMD patients after RRD repair. Our study suggests that approximately 58% of patients with AMD can expect to maintain functional vision better than 20/200. We conclude that AMD patients can achieve functional vision after RRD surgery, similar to those without AMD. These findings may be helpful in guiding realistic expectations of AMD patients with RRD.

Evaluating of the correlation between quality of life, life expectancy and mortality rate is an important problem of modern ophthalmology. Many researchers note that eye pathology, which leads to a visual acuity decrease and blindness, has a significant impact on the mortality rate of the population. This review of literature is dedicated to studies examining the impact of eye diseases on the mortality rate of the population. (For citation: Zolotarev AV, Karlova EV, Miroshnichenko EV. Influence of eye diseases on the mortality rate of the population. ­Oph­thal­mology Journal. 2018;11(1):47-53. doi: 10.17816/OV11147-53).

Background: Direct traumatic optic neuropathy (TON) carries a poor prognosis. However, the outcome of this injury is diverse and is related to time to treatment and treatment protocol. Objective: To evaluate the outcomes of the combined treatment protocol in patients with direct TON. Materials and Methods: The authors retrospectively reviewed the medical records of patients between January 2015 and August 2019. Main outcome was visual acuity (VA) improvement after the treatment. Results: Thirteen patients (15 eyes) were included. The mean age was 38.61 years with a range of 13 to 65 years. Initial VA varied from no light perception (NPL) in seven eyes of six patients, light perception (PL) in one eye, counting fingers in two eyes, 20/200 in three eyes, and 20/60 in two eyes. Average timing to treatment was 2.8 days (range 0 to 7 days). There were no side effects of high-dose corticosteroids treatment in all patients. During a follow-up period of three months, six of 13 patients (46.1%) had VA improvement. Conclusion: Despite poor prognosis of direct TON, the combined treatment protocol provides a favorable successful rate with most patients on having stable vision, and some having visual improvement from reducing intracanalicular pressure of the optic nerve.

Purpose. To investigate the efficacy and safety of combined vitrectomy with tumor resection in the treatment of retinal vasoproliferative tumors (RVPT). Methods. Retrospective study. RVPT patients who underwent vitreous surgery at the Eye Hospital of Wenzhou Medical University from January 2011 to July 2017 were included. The main outcomes included treatment type, tumor activity, and best-corrected visual acuity (BCVA). Results. Altogether, 16 patients with 17 eyes were enrolled with follow-up of no less than 6 months. Eight eyes were in the resection treatment group (Group R) and 9 eyes were in the conservative treatment group (Group C). Female (69%) were more common. The mean age was 50 (49.72 ± 12.92) years. Fifteen patients got unilateral onset and only one patient suffered bilaterally. The common symptoms were decreased visual acuity, floaters, and visual distortion. The preoperative BCVA ranged from hand movement to 20/20, with an average of 0.82 ± 0.75 LogMAR. Patients were all not high myopia, with a mean axial length of 23.27 ± 0.27 mm (21.61 mm to 24.67 mm). Of the retinal diseases, the epiretinal membrane was the most common, followed by vitreous hemorrhage, uveitis, subretinal fluid, and so on. Compared with the baseline BCVA, it improved more at postoperative 6 months and the last visit in Group R than in Group C (P=0.006 and P=0.033). The BCVA-improved 0.2 LogMAR or above in 6 months was 2 eyes in Group C and 7 eyes in Group R. All tumors in Group R were completely resected, whereas three in Group C (33.3%) had definite activity (P=0.008). In all samples, tumors were located on the inner side of the retina and had small vessel wall thickening and hyaline degeneration. The degree of astrocyte proliferation varies widely among different tumors. Conclusions. RVPT was more likely to occur in nonhigh myopia patients. Epiretinal membrane and vitreous hemorrhage were the main causes for vitreous surgery in RVPT patients. Compared with conservative treatment, surgical resection of the tumor is more beneficial to patients on visual acuity recovery and preventing tumor relapse. It is a safe and effective way to treat RVPT.

Theories of spatial representation in blind people have focused on the type of representation of which they, as a group, are capable. This approach overlooks an important issue, namely, the differences among individual blind people and the effects that these differences have on the way spatial information is represented. Data from another article by the author on the same study of spatial representation in blind children were subjected to two step-wise regression analyses to determine the relationships between several subject-related variables and responses to “map” (cognitive map) and “route” (sequential memory) questions about the position of furniture in a recently explored room. The independent variables accounted for 70 percent of the variance on map questions but only 46 percent of the variance on route questions. On map questions, general intellectual ability correlated positively with performance (p < .01), children with visual acuity better than light perception in the first 3 years of life performed better than those with less early vision (p < .05), and children who became blind from retrolental fibroplasia performed more poorly than those whose blindness was due to other causes (p < .05). Fewer independent variables contributed to the variance in performance on route questions. Again children with visual acuity better than light perception in their first 3 years performed better than those with less early vision.

Abstract Background To evaluate the epidemiology of endophthalmitis cases related to ocular trauma, including visual acuity during and 1 year after trauma, source of trauma and method of treatment. Methods A retrospective study analyzed the epidemiological data of patients with a clinical presentation of endophthalmitis after ocular penetrating trauma between January 2012 and January 2017 at Escola Paulista de Medicina/UNIFESP, a hospital in São Paulo, SP, Brazil. Results A total of 453 patients with antecedent open globe trauma were evaluated, among these, 30 patients with suspected endophthalmitis. All patients were male. The time interval between trauma and ophthalmological evaluation and collection of vitreous and aqueous material was 1 day in 36.66%, 2–7 days in 43.44%, 7–14 days in 10% and more than 15 days in 10% of patients; 66.66% had positive cultures. 11 patients had intraocular foreign body. One year after trauma, visual acuity was classified as no light perception (NLP) in 33.33%, light perception in 6.66%, hand motion in 13.33%, counting fingers in 13.33%, and better than 20/400 in 20% of patients. Considering presence of intraocular foreign body, initial visual acuity and symptoms onset time, only initial visual acuity showed as better prognostic factor in final visual acuity. Conclusion Endophthalmitis is a severe ocular inflammatory condition that may lead to irreversible vision loss. Initially only one patient had visual acuity of NLP, but after 1 year, 33% showed visual acuity of NLP, and only 20% had visual acuity better than 20/400, what is consistent with a severe infection with a guarded prognosis. The high incidence of endophthalmitis after ocular penetrant trauma justifies distinct treatment and greater attention.

The focus of the present review of literature is keratoconus, a progressive thinning of the cornea. Because keratoconus usually induces irregular astigmatism, the most affected patients experience a decreased visual acuity that limits the correction using ophthalmic lenses. The CLEK (Collaborative Longitudinal Evaluation of Keratoconus) is a study carried out in several centers with the aim of describing the evolution and associations between the visual and physiological manifestations of keratoconus. Since the treatment of keratoconus varies according to its severity, this paper proposes a summary of the results of the CLEK and a review of the therapeutic options.
