Posterior Polar Cataract

Young patient was referred to us for cataract surgery removal and artificial intraocular implant , due to progressive vision loss. Slit lamp examination revealed posterior polar cataract. Posterior  Polar cataract represent a medically and surgically unique subset of cataract that often arise at the end of a hyaloid artery remnant, which can result in a range of pathology from the benign "Mittendorf dot" to a more clinically relevant cataract.[1] Capsular fragility has been reported [2] that is why surgical technique must place the least amount of stress possible on the posterior capsule. [2] The surgeon should avoid hydrodissesction and the removal of the nucleus should be performed in a very stable anterior chamber. After lens material phacoemulsification, manual manipulation of posterior polar plaque should be attempted. If posterior capsular rupture occurs, anterior vitrectomy should be done before placing the intraocular lens.

Purpose. To report the application of 25 MHz B-scan ultrasonography (MHzB) to determine the integrity of the posterior capsule (PC) in posterior polar cataract (PPC). Methods. Patients with whom PPC was clinically diagnosed using slit lamp microscopy who underwent 25 MHzB before phacoemulsification were retrospectively reviewed. The status of the PC was determined by 25 MHzB before phacoemulsification and confirmed during cataract surgery. Results. In total, 21 eyes in 14 clinically diagnosed PPC patients were enrolled in this study. Out of 25 MHzB images, 19 PCs were found to be intact, while 2 showed dehiscence before cataract surgery. During phacoemulsification, 17 PCs were observed to be intact, while 4 PCs showed posterior capsule rupture (PCR). These 4 PCR cases included the above 2 eyes, in which preexisting dehiscence was detected by 25 MHzB. The other 2 PCR cases showed high reflectivity between high echoes in posterior opacities and the PC, indicating synechia between the PPC and PC. Conclusion. This is the first report to show that 25 MHzB can be used to clearly visualize the status of the PC in PPC. These results, in turn, could be used to select the appropriate treatment and to thereby avoid further complications during PPC surgery.

Posterior Polar Cataract

Introduction: Posterior polar cataract (PPC) is a relatively uncommon form of congenital cataract accounting for around 0.5% to 2% of the total cataract. A posterior polar cataract presents a special challenge to the phaco surgeon because of its predisposition to posterior capsular dehiscence during surgery. Incidence of posterior polar cataract ranges from 3 to 5 in 1000. Methodology: Prospective descriptive study done at Biratnagar Eye Hospital from December 2016 to March 2017. A detailed slit-lamp biomicroscopy of the anterior segment, intraocular pressure and dilated fundus examination was performed in all patients after checking for visual acuity and refraction. Result: Total of 60 eyes of 59 patients was included in the study, out of which only 5% had posterior capsular rupture during surgery. Mean age of patients in our study was 49.35 +_ 9.5yrs (range 35-73yrs). There were 34 male patients and 26 female patients. Mean axial length was 23.40mm. Out of 60 eyes, 12 eyes had bilateral posterior polar cataract. Mean preoperative visual acuity was 0.949 while first post-operative day visual acuity was 0.5137, which was statistically significant (P < 0.0001) (paired t test). Conclusion: Intraoperative complications during posterior polar cataract surgery can be minimized by careful and appropriate surgical procedure.

Penetrating Ocular Trauma

Endophthalmitis refers to inflammation of both the anterior and posterior intraocular chambers and their structures. This vision-threatening condition occurs in three principal scenarios: penetrating ocular trauma, after intraocular surgery, and in systemically infected (often immunocompromised) patients. Endophthalmitis presents with marked intraocular inflammation, often with hypopyon. Patients report pain and significant vision loss out of proportion to typical post-operative complaints. It is distinguished from uveitis by both history and slit lamp examination. Endophthalmitis is an ophthalmic emergency. Same day ophthalmology consult/referral is mandatory. Vision is threatened over the course of hours. Treatment includes prompt intravitreal injection of antibiotics by an ophthalmologist. Systemic therapy should occur only in in endogenous infections, continuing until cultures clear.

Purpose. To report a case of acute hydrops in a 10-year-old child with advanced keratoconus.Case Presentation. A ten-year-old boy diagnosed as having right eye (RE) infectious keratitis, not responding to antimicrobial therapy, was referred to our hospital. The diagnosis of infectious keratitis was established one month prior to his presentation following an episode of acute corneal whitening, pain, and drop in visual acuity. Topical fortified antibiotics followed by topical antiviral therapy were used with no improvement. Slit lamp examination showed significant corneal protrusion with edema surrounding a rupture in Descemet’s membrane in the RE. The diagnosis of acute corneal hydrops from advanced keratoconus was highly suspected and confirmed with corneal topography.Conclusion. Although a relatively rare disease at the age of 10 years, keratoconus can be rapidly progressive in the pediatric group. Keratoconus should always be considered in the differential diagnosis of progressive vision loss in this age group.

AIM: To determine the prevalence and visual outcomes after cataract surgery in different LIG patients METHODS:In this prospective study 50 patients were taken into study. Detailed history was taken and slit lamp examination was done & IOP was recorded by AT. All the patients were treated preoperatively appropriately. Patients were operated with SICS with PC IOL implantation and Peripheral Iridectomy.During follow up a detailed Ocular examination was done including Refraction using snellens chart and IOP measurement with AT. RESULTS: Among 50 patients 21(42%)were male patients and 29(58%)were female. Maximum patients had Phacomorphic Glaucoma accounting 72% (36patients) and Phacolytic Glaucoma 24%. Highest percentage was among 40-49mmHg (52%) followed by 30-39mmHg (36%) and >50mmHg (10%). Highest patients were between 10-19mmHg (76%). Visual acuity on admission, highest patients were seen in HM positive (64%) followed by PL+(32%). Even No PL were also seen (4%). On follow up after 6weeks ,majority were seen between 6/12- 6/18(52%) CONCLUSION: LIG is an important vision-threatening disease presenting as a painful red eye. It is remaining as one of the important cause of Blindness not only because of Senile cataract but even after cataract surgery due to Glaucoma caused by neglected cataractous lens.Hence, importance should be given for timely surgery for better visual outcome .

A 31-year-old male patient presented with the complaint of progressive vision loss in his left eye. Slit-lamp examination showed posterior embryotoxon, iris hypoplasia, and iridocorneal adhesion in both eyes, corectopia in the right, and peripheral inferior thinning and ectasia in the left eye. Corneal topography showed slightly asymmetric bowtie pattern in the right eye and crab-claw pattern in the left eye. Topographic examination was compared with his previous topography. The comparison showed 1.6-D steepening of maximum keratometry ( Kmax) and 22-µm decrease of thinnest corneal pachymetry. Corneal crosslinking treatment was performed on the left eye. At the postoperative 28-month follow-up visit, Kmax decreased from 54.1 to 53.0 D and corrected distance visual acuity improved to 20/20 with scleral lens. This is the first reported a case with Axenfeld–Rieger syndrome and pellucid marginal degeneration association. We suggest that corneal crosslinking can be useful for management of pellucid marginal degeneration and longer follow-up might be needed in order to corroborate the effectiveness of the corneal crosslinking procedure.

The purpose of this manuscript is to report the case of a 12-year-old patient who presented for routine ophthalmic examination after congenital cataract surgery performed at 2 months of age. The patient was diagnosed with bilateral Brown-McLean syndrome by slit lamp examination. No treatment was required because the patient was asymptomatic and had a clear central cornea. This is the first described case of Brown-McLean syndrome in a pediatric patient, representing the importance of clinical examination in the pediatric age group after cataract surgery because of the risk for patients of developing peripheral edema.

A case report on a 49-year-old female with diagnoses of ocular hypertension in her left eye (LE) treated with 250 mg/day acetazolamide for 2 years. During the slit-lamp examination, complete occlusion of both iridocorneal angles was detected. Intraocular pressure (IOP) was 10 and 35 mmHg in the right eye and LE, respectively. Phacotrabeculectomy was performed in the LE. After 1 month of the procedure, the patient developed a slowly progressive miopization from −1 to −3 diopters (D) the following months. Approximately 3 months after surgery, the patient developed an episode of acute pain, athalamia, and IOP 45 mmHg in her LE. Late-onset malignant glaucoma was suspected and the patient was treated with topical hypotensive and cycloplegic agent until a prompt vitrectomy was performed. Deepening of the anterior chamber and restoration of IOP to normal range was obtained after surgery.

Subsequent Degradation

Cataracts are a leading cause of blindness worldwide. Surgical removal of cataracts is a safe and effective procedure to restore vision. However, a large number of patients later develop vision loss due to regrowth of lens cells and subsequent degradation of the visual axis leading to visual disability. This postsurgical complication, known as posterior capsular opacification (PCO), occurs in up to 30% of cataract patients and has no clinically proven pharmacological means of prevention. Despite the availability of many compounds capable of preventing early steps in PCO development, there is currently no effective means to deliver such therapies into the eye for a suitable duration. To model a solution to this unmet medical need, we fabricated acrylic substrates as intraocular lens (IOL) mimics scaled to place into the capsular bag of the mouse lens following a mock-cataract surgery. Substrates were coated with a hydrophilic crosslinked acrylate nanogel designed to elute Sorbinil, an aldose reductase inhibitor previously shown to suppress PCO. Insertion of the Sorbinil-eluting device into the lens capsule at the time of cataract surgery resulted in substantial prevention of cellular changes associated with PCO development. This model demonstrates that a cataract inhibitor can be delivered into the postsurgical lens capsule at therapeutic levels.
