Macular hole is a frequent retinal pathology that depends on the clinical ability of a specialist for its diagnosis. The purpose of this study is to document the clinical findings used by ophthalmology residents for a presumptive diagnosis of macular hole before confirmation with optical coherence tomography (OCT).
A retrospective analysis of 105 patients (n= 115 eyes) that attended an initial visit between January 2015 to December 2015 with a macular hole diagnosis. The clinical findings were considered as follows: Best Corrected Visual Acuity (BCVA), Amsler test and fundoscopic characteristics such as posterior vitreous detachment (PVD), macular hole (MH), epiretinal membrane (ERM), macular folds and Watzke-Allen sign. These findings were documented from each evaluation and total frequencies were calculated.
: 115 eyes were analyzed, 65 being women and 40 being men. The median age of diagnosis was 59.1 and the right eye was found to be affected in 56 (49.1%) patients, therefore being the most common. Only 10 (8%) patients had both eyes affected. The median BCVA was 0.80 LogMar. A total of 17 (16%) Amsler tests were done, of which 9 (52%) were positive for metamorphopsia and 2 (11%) for central scotoma. The Watzke-Allen sign was evaluated in 59 (51.7%) patients, where 43 (73%) were found positive and 13 (22%) negative. The fundoscopic examination revealed PVD in 7 (5%) patients, MH in 105 (92%) patients, ERM in 25 (22%) patients and macular folds in 7 (6%) patients.
The presumptive clinical diagnosis of macular hole done by residents did not require a systematic and detailed exploration of the patient. The image of macular hole and the positive Watzke-Allen sign were the most conclusive data and the most used to consider the diagnosis during baseline visit. The diagnosis was confirmed afterwards with an OCT at the retina department.
