Iris Atrophy

Purpose. To report an unknown complication of laser in situ keratomileusis (LASIK) surgery.Case Presentation. A 28-year-old female presented with photophobia and glare to our eye service. She stated in her medical history that she had undergone femtosecond assisted LASIK surgery in both eyes 15 months ago and her symptoms started just after this surgery. On admission, her best-corrected visual acuity was 10/10 in both eyes. She had mydriatic pupils with no direct light reflex. Examination of the anterior segment revealed bilateral iris atrophy projecting within the LASIK ablation zone and a transillumination defect was remarkable on the slit lamp examination.Conclusion. We hypothesized that this condition may have been caused by the abnormally increased IOP that resulted in ischemia in the iris vascular plexus during the suction process of surgery.

Abstract Background: Laser in situ keratomileusis (LASIK) is increasingly used worldwide to correct a wide range of refractive errors. Toxic anterior segment syndrome (TASS), a noninfectious inflammatory disease with symptoms and signs that resemble bacterial infection, is a rare complication of LASIK. Case presentation: We report a case of TASS in a 42-year-old male patient after LASIK surgery in both eyes for hyperopia. Diagnosed clinically. Discussion and conclusion: Little information about complications after LASIK is available. TASS is a general term used to describe acute, sterile postoperative anterior segment reactions. Patients with TASS will often experience blurry vision with or without pain within 12 to 48 hours after surgery. Steroids have shown to be effective in resolving the inflammatory response, reducing the pain and recovering the vision.

A 40-year-old male patient referred to the ophthalmologic emergency room for complaints of diminution of vision in the left eye since three months after a trauma. Examination of the left eye showed a corrected visual acuity of 20/70. Slit-lamp examination revealed a rosette cataract (Figure 1). The patient underwent phacoemulsification with implantation of an IOL in the bag. The rosette cataract is a posterior subcapsular cataract due to a violent contusion with a closed globe. It can develop in the hours that follow, or on the contrary several years later.

AIM: To investigate and evaluate healing patterns around flaps made with different side-cut angulations after femtosecond laser in situ keratomileusis (FS-LASIK). METHODS: Thirty-four patients (68 eyes) received a 90° side-cut (n=34) or a 120° side-cut flaps (n=34) made with a femtosecond laser. One day, 1wk, 1 and 3mo postoperatively, side-cut scar was evaluated under slit-lamp photography according to a new grading system (Grade 0=transparent scar, 1=faint healing opacity, and 2=evident healing opacity). In vivo corneal confocal microscopy and anterior segment optical coherence tomography (AS-OCT) were used to observe wound-healing patterns around flap margin in the two groups. Sirius Scheimpflug Analyzer was also used to analyze higher order aberrations 3mo after surgery. RESULTS: There were no significant differences in flap wound-healing patterns at each follow up between the two groups (P>0.05). Three months after surgery, the flap edge scar classified as Grade 0 had excellent apposition and rapid nerve regeneration. At 3 mm and 5 mm pupil diameters, there were significant differences in trefoil aberrations between the two groups (P<0.05), but no statistically significant differences were found in total higher order aberrations (HOAs), spherical aberrations or coma in any of the pupil size conditions (P>0.05). CONCLUSION: Flap edge scars classified as Grade 0 have excellent apposition and rapid nerve regeneration, and 120° side-cut angle flaps induce less trefoil aberrations after FS-LASIK.

Abstract Background A persistent hyaloid artery is a rare fetal remnant. Several complications such as amblyopia, vitreous hemorrhage, and retinal detachment have been reported. Here, we present a case of vitreous hemorrhage with a persistent hyaloid artery. Case presentation A healthy 16-year-old male presented with blurred vision in his left eye. Vitreous hemorrhage occurred and absorbed spontaneously. Slit-lamp examination demonstrated a Mittendorf’s dot and fundus examination revealed a persistent hyaloid artery. Optical coherence tomography showed a Bergmeister’s papilla. The blood flow of the persistent hyaloid artery via the Bergmeister’s papilla was found by OCT angiography. Conclusion The persistent hyaloid artery should be considered as a cause of spontaneous vitreous hemorrhage of young healthy patient. The OCT angiography will be a useful noninvasive approach to confirm the patency of the persistent hyaloid artery.

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.

This report describes a case of Scheimpflug topography oriented adequate repositioning of a misaligned thick free flap after laser in situ keratomileusis (LASIK). A 24-year-old patient consulted for irregular astigmatism and disoriented free right eye flap. The patient previously underwent binocular LASIK at a private clinic. During the right eye surgery, the flap was repositioned after laser ablation due to the free flap. The free flap was not repositioned to its original configuration due to insufficient preoperative corneal marking. On examination, the uncorrected visual acuity was 0.4, and refractive power was +2.00 Dsph with −4.25 Dcyl axis 66 in the right eye. Scheimpflug topography revealed irregular right eye astigmatism. The sagittal curvature of topography showed a 40° counterclockwise misalignment of the steep axis of the cornea. The free flap was repositioned by 40° clockwise rotation. After this, the refractive corneal power improved to −1.00 Dsph with −1.00 Dcyl Axis 19 in the right eye. The uncorrected and best-corrected visual acuity improved to 20/30 and 20/25 (x − 0.25Dsph −1.25 Dcyl A20), respectively. This is the first report on free flap repositioning using Scheimpflug topography. As proper flap positioning was compromised because of the free LASIK flap with no preoperative corneal marking, the flap was effectively repositioned using Scheimpflug topography.

BACKGROUND Serpiginous choroiditis (SC) is an intraocular inflammatory disorder displaying a geographic pattern of choroiditis, extending from the juxtapapillary choroid and intermittently spreading centrifugally. It involves the overlying retinal pigment epithelium (RPE), the outer retina including the choriocapillaries and the choroid.1,2,3 Infectious diseases like tuberculous (TB) uveitis, herpes simplex virus (HSV) uveitis whose fundus changes mimic SC are termed as serpiginous-like choroidopathy (SLC). On slit lamp examination, anterior segment usually appears quiet, non-granulomatous anterior uveitis with mild vitritis and / or fine pigmented cells within the vitreous can be seen. The pattern of fundus involvement varies between the two groups. Fundus fluorescein angiography and indocyanine green angiography (FFA and ICG) are important modalities of investigation that help in differentiating the pattern of involvement and confirming clinical findings. The duration of follow up, reactivation of lesions and complications vary. Hence, it is important to differentiate between SC and SLC for proper diagnosis and appropriate management. The aim of this study is to highlight important features of serpiginous choroiditis and serpiginous like choroidopathy that will aid in the correct diagnosis of these two entities. METHODS This is a retrospective study of 40 patients. Following variables were analysed - age, gender, laterality, visual acuity, and intraocular inflammation through slit lamp examination, pattern of involvement, choroidal-neovascularization, reactivation, clinical investigations and diagnosis. RESULTS 32 patients had serpiginous choroiditis (SC) and eight patients had serpiginous like choroiditis (SLC). Mean age was 50 and 51 years (SC and SLC respectively). Males were predominantly affected (65.5 % in serpiginous choroiditis and 62.5 % in serpiginous like choroiditis). Bilaterality was 80 % in SC-group and 46 % in the SLC-group. Vitreous haze was lesser than or equal to 1 + in SC group. The juxtapapillary-area was involved in 90 % in SC eyes and 0 % in SLC-group. Midperiphery of fundus was involved in 54 % of SLC-group. Reactivation is more common in SLC group than in SC group in a follow up period of one year. Choroidal-neovascularisation was found in two patients only in SLC-group. CONCLUSIONS In cases where vitreous haze is greater than 1 + with unilateral involvement and disease free peripapillary area is present, an infectious aetiology has to be strongly suspected, as an immunomodulatory therapy could have severe consequences.
