Rare occult macular dystrophy with a pathogenic variant in the RP1L1 gene in a patient of Swiss descent.

Purpose: We report a first case of bilateral occult macular dystrophy (OMD) with a c.133C>T (p.Arg45Trp) pathogenic variant in the retinitis pigmentosa 1-like 1 () gene in a patient of Caucasian Swiss decent.

Full-field sensitivity threshold and the relation to the oxygen metabolic retinal function in retinitis pigmentosa.

Purpose: The aim of our study was to evaluate retinal function with white light dark-adapted full-field sensitivity threshold (FST) and find possible correlations with metabolic function measured with retinal oximetry (RO) in patients with retinitis pigmentosa (RP).

Methods: In this prospective observational study (BASEC 2020-00,122), FST and RO measurements were performed on 66 RP eyes (33 subjects, 12♀ 21♂) aged between 18 and 80 years (mean 43.2 years); all eyes were graded for disease severity.

Metabolic Long-Term Monitoring of Transcorneal Electrical Stimulation in Retinitis Pigmentosa.

Introduction: Transcorneal electrical stimulation (TES) is a new therapeutical approach for retinitis pigmentosa (RP). With progression of RP, degeneration of photoreceptors results in lower oxygen consumption of the retina. Retinal oximetry (RO) is a noninvasive method to analyze oxygen saturation in retinal vessels and has shown promising short-term results as a therapy monitoring tool for TES.

Optical coherence tomography angiography findings in patients undergoing transcorneal electrical stimulation for treating retinitis pigmentosa.

Purpose: Transcorneal electrical stimulation (TES) is a novel treatment approach for patients with retinitis pigmentosa (RP). The aim of our study was to observe changes in optical coherence tomography angiography (OCTA) that would be attributed to TES treatment.

Methods: A total of 73 eyes were included: 43 eyes of 22 subjects (11 ♀, 11 ♂) suffering from RP were examined at baseline (BL), after first stimulation (TS), 1 week (1W), and 6 months (6M) after treatment initiation and were compared with 30 control eyes of 15 subjects (8 ♀, 7 ♂).

Intraocular Pressure Elevation in Keratoconus with Coexisting Pseudoexfoliation Glaucoma: How Important is the Method of Measurement?

Objective: In this report, we investigated the association between the intraocular pressure (IOP) values by two different measurement methods and the corneal biomechanical properties in a patient with keratoconus and secondary glaucoma due to pseudoexfoliation syndrome who developed a marked elevation of intraocular pressure in the right eye.

Methods: IOP was measured over a period of 3 days with Goldmann applanation tonometry (GAT) and dynamic contour tonometry (Pascal tonometry, DCT). Corneal hysteresis (CH) and corneal resistance factor (CRF) were estimated with the aid of an ocular response analyzer (ORA).
