UNILATERAL CHEMOSIS, BULLOUS SEROUS RETINAL DETACHMENT, AND PRESUMED BACILLARY LAYER DETACHMENT IN SEVERE PREECLAMPSIA

Subretinal Drusenoid Deposits in a Patient With HELLP (Hemolysis, Elevated Liver Enzymes, Low Platelet) Syndrome

Subretinal drusenoid deposits (SDD) are findings that can be observed in age-related macular degeneration as well as in ischemic ocular diseases. These deposits are believed to be of prognostic importance, as they have been shown to be associated with choroidal neovascularization. HELLP (hemolysis, elevated liver enzymes, low platelet) syndrome is a condition linked with severe preeclampsia, and it presents ocular findings such as hypertensive retinopathy, serous retinal detachment, and cortical visual impairment. This case report discusses the presence and course of SDD in a female patient who presented with hypertensive retinochoroidopathy secondary to HELLP syndrome.

Bacillary layer detachment as an inflammatory biomarker in toxoplasmosis retinochoroiditis: serial evolution on optical coherence tomography

We describe the clinical course and serial evolution of bacillary layer detachment (BALAD) on optical coherence tomography (OCT) in toxoplasmosis retinochoroiditis and its importance as an inflammatory biomarker. Colour fundus photography and swept-source OCT of the BALAD were done at the time of presentation and subsequently at 1 week, 2 weeks, 4 weeks and at 11 weeks. Treatment involved oral trimethoprim (160 mg) + sulphamethoxazole (800 mg) two times per day, started at presentation for 2 months. Oral prednisolone was started after 1 week at a dose of 50 mg a day and tapered weekly over the next 5 weeks. The BALAD initially increased after starting treatment with trimethoprim-sulphamethoxazole and regressed within 1 week after initiation of oral prednisolone. Best corrected visual acuity improved to 20/40 from 20/160 at presentation (Snellen equivalent). This suggests that BALAD is an indicator of an acute inflammatory event and the accumulated fluid is secondary to retinal and choroidal inflammation.

Exudative Retinal Detachment and Ciliochoroidal Effusion in Preeclampsia

Purpose: To describe a novel case of focal exudative retinal detachment, choroidal effusion, and acute angle closure in preeclampsia. Methods: A case report is presented. Results: A 37-year-old woman at 38 weeks gestation presented with 2 weeks of progressive blurred vision in the left eye. She had a visual acuity (VA) of 20/800 and an intraocular pressure (IOP) of 26 mm Hg in the left eye (compared with 17 mm Hg in the right eye). Examination showed subretinal fluid in the posterior pole, ciliochoroidal effusion, and angle closure in the left eye without pathology in the right eye. She was found to have hypertension and proteinuria consistent with preeclampsia. The visual symptoms resolved after delivery. At the 1-month follow-up, she had a VA of 20/60 OS, symmetric IOPs, and resolved subretinal and choroidal effusions. Conclusions: To our knowledge, this is the first reported case of ciliochoroidal effusion in the setting of preeclampsia. It may aid in the diagnosis of preeclampsia's ocular manifestations and broaden pathophysiological understanding.

Bacillary Layer Detachment in a Korean Cohort with Neovascular Age-Related Macular Degeneration

PURPOSE

To evaluate the incidence and characteristics of bacillary layer detachment (BALAD) in neovascular age-related macular degeneration (AMD).

METHODS

This retrospective study was performed at Kim's Eye Hospital in South Korea. Patients who were diagnosed with neovascular AMD between January 2017 and December 2017 were included. The incidence of BALAD was compared among different types of macular neovascularization. The best-corrected visual acuity (BCVA) and central retinal thickness (CRT) at diagnosis were compared between patients showing BALAD at diagnosis and those who did not.

RESULTS

Among the 442 patients included, BALAD was observed in 20 patients(4.5%). There was a significant difference in the incidence of BALAD between type 1 MNV(2.7%), type 2 MNV(12.5%), and type 3 MNV (0%)(P<0.001). The BCVA was significantly worse (mean 1.26±0.79 vs 0.62±0.50, P=0.001), and the CRT was significantly greater (mean 648.2±211.1 µm vs 464.0±175.5 µm, P<0.001) in patients with BALAD than in those without it. After anti-vascular endothelial growth factor therapy, all BALADs resolved.

CONCLUSIONS

This study first reported the incidence of the BALAD in neovascular AMD in Korean population. The incidence of BALAD was the highest in type 2 MNVs. BALAD generally develops in eyes with great macular thickness and poor visual acuity.
