Favorable outcome after choroidal drainage for postoperative kissing suprachoroidal hemorrhage following trabeculectomy in a high myopic vitrectomised eye.

A 39-year-old lady with past history of vitreoretinal surgery for retinal detachment and cataract surgery with Intraocular lens implantation was diagnosed as uncontrolled glaucoma. She had high myopia. She underwent Trabeculectomy and following which she presented with massive suprachoroidal hemorrhage in the first postoperative day with severe loss of vision. This case depicts the risk of suprachoroidal hemorrhage in a high myopic vitrectomised eye following glaucoma filtration surgery. It also demonstrates a favorable outcome following intervention for postoperative Suprachoroidal hemorrhage. At present, there is no evidence in literature of such event in a high myopic Vitrectomised eye following Trabeculectomy.

Case control analyses of acute endophthalmitis after cataract surgery in South India associated with technique, patient care, and socioeconomic status.

Purpose. We investigated acute endophthalmitis incidence following cataract surgery vis-a-vis the current technological and postoperative care changes in higher and lower socioeconomic categories of patients in South India. Methods. In a retrospective case control study, we analyzed 62 cases of acute endophthalmitis and 5 controls for each endophthalmitis case from 46,095 cataract surgeries done between years 1993 and 1998. The time period covered the transition of surgical technique and after care. In addition, we analyzed systemic diseases, surgeon factor, habitat, and socioeconomic status. Results. Clinical and culture positive endophthalmitis incidence were 0.13% and 0.07%, respectively. Differential incidence of 0.10% and 0.17% for in- and ambulatory care surgeries, respectively, was close to statistical significance (P = 0.054). Lower economy category ambulatory patients had higher risk of infection. Conclusion. Ambulatory cataract surgery carried additional risk for post-operative infection in lower socioeconomic group. Improved health education could ensure greater safety.

Modification of screening criteria for retinopathy of prematurity in India and other middle-income countries.

PURPOSE: To determine the gestational age and birth weight of premature babies who developed vision-threatening severe retinopathy of prematurity. DESIGN: Prospective observational study of babies at risk of blindness due to retinopathy of prematurity. METHODS: Data pertaining to all babies who underwent laser treatment or surgery for acute retinopathy of prematurity and those who had cicatricial retinopathy of prematurity were prospectively collected. The gestational age and birth weight were evaluated to establish screening criteria. RESULTS: In 120 babies, the mean gestational age was 29.6 weeks (range 26 to 36 weeks). The birth weight of 115 babies ranged from 710 to 2000 g (mean 1254.5 g, SD 280.8). Birth weight was not available for five babies. Only one baby had a gestational age of >35 weeks. CONCLUSIONS: Ocular morbidity related to retinopathy of prematurity was seen in bigger and more mature babies. This study provides a scientific basis for establishing screening criteria for retinopathy of prematurity in South India and other middle-income countries.

Comparison of mean macular thickness using optical coherence tomography and visual acuity in diabetic retinopathy.

BACKGROUND: The purpose of the present study was to quantitatively assess the mean macular thickness in diabetic patients using optical coherence tomography and its correlation with visual acuity. METHODS: A prospective case series study was undertaken of consecutive diabetic patients referred to a tertiary eye care centre for an eye check up from January 2003 to June 2003. One hundred and five eyes from 55 patients with varying degree of diabetes underwent optical coherence tomography examination. The study patients were divided into four groups: group I, non-proliferative diabetic retinopathy (NPDR); group II, NPDR with clinically significant macular oedema (CSME); group III, proliferative diabetic retinopathy (PDR); and group IV, PDR with CSME. RESULTS: The mean macular thickness of the entire group was 256.0 +/- 129.7 microm. A positive correlation (r = 0.424, P < 0.0001) was evident between mean macular thickness and visual acuity. CONCLUSION: Optical coherence tomography is a useful tool for objectively monitoring macular thickness in patients with diabetic retinopathy. Mean macular thickness correlates with visual acuity.

Role of photodynamic therapy in polypoidal choroidal vasculopathy.

PURPOSE: To evaluate photodynamic Therapy (PDT) with Verteporfin for polypoidal choroidal vasculopathy (PCV) involving the fovea in Indian eyes, through a retrospective interventional case series. MATERIALS AND METHODS: We retrospectively reviewed the records of 9 patients (9 eyes) diagnosed to have PCV with foveal involvement between September 2001 and October 2002. RESULTS: Nine eyes underwent PDT for PCV. Follow-up ranged from 12 to 16 months. Initial visual acuity (VA) ranged from 1/60 to 6/12 and final VA varied from 1/60 to 6/9 at the end of follow-up. VA improved in 4/9 eyes (44.4%) by one line and remained unchanged in 5/9 eyes (55.6%), hence it was considered stabilized in all eyes. No adverse effects or events were observed during or after treatment with verteporfin. CONCLUSION: PDT may be beneficial for PCV with foveal involvement. Its long-term efficacy requires to be evaluated.

Optical coherence tomographic evaluation of foveal pseudocyst in the formation of macular hole.

Optical coherence tomographic documented progression of foveal pseudocyst in a vitrectomised eye to full thickness macular hole is reported. Muller cell alteration and other centrifugal forces are possible pathomechanisms.
