To describe the findings and new interpretation methods of retinal thickness maps in the setting of hydroxychloroquine (HCQ) therapy.A case series of 27 patients with a history of HCQ intake of more than 5 years and 21 normal subjects as the control group were studied. Patients were tested using swept-source optical coherence tomography (OCT). Custom-made 10 × 10 retinal thickness pixel maps of the 6 mm⨯6 mm area centered on the fovea were created for the full, inner, and outer retina of each eye and normal values obtained from the control group were used to calculate the statistical significance of each pixel and highlight suspicious pixels. A pixel was shown with light or dark gray color if its p value was ≤ 0.05 or ≤ 0.01, respectively. Cross-sectional OCT images and visual fields were examined as well and used to confirm the diagnosis of HCQ retinopathy.The pixel outer retinal thickness maps appeared accurate in detecting lesions even in eyes with unremarkable full retina thickness maps. The size and location of atrophic retinal defects were shown on pixel maps. Outer retinal thickness maps were able in differentiating outer retinal thinning from inner retinal thinning as the hallmark of HCQ retinopathy.Outer retinal thickness pixel maps can be used for the screening of HCQ retinopathy.

Purpose To measure the foveal avascular zone (FAZ) areas and vessel densities of patients with diabetic retinopathy and to study their relationship with diabetic cystoid changes and retinal thickness. Methods Prospective case series of 51 eyes of 31 patients with diabetic retinopathy. The eyes were grouped based on the presence or absence of cystoid edema and evaluated using optical coherence tomography angiography. The FAZ areas and vessel density were compared. Results The FAZ area at the superficial capillary plexus level was equal between the eyes with and without cystoid edema. Vessel density did not differ as well. There was no correlation with retinal thickness. In eyes with cystoid changes, FAZ area changes at the deep capillary plexus level were difficult to interpret. Conclusion The FAZ area and vessel density at the superficial capillary plexus level are reproducible and independent of the presence of cystoid edema.

The aim of this article is to describe the "mini tarsal strip procedure", a form of lateral canthal tendon plication to tighten the lower lid and give a better apposition of the lower eyelid to the globe. We describe this procedure in the context of transconjunctival lower lid blepharoplasty.

A 41-year-old man presented with a 7-year history of gradually increasing right proptosis and a 2-year history of decreased vision and limited eye movements. Right proptosis (11 mm), limitation of movement in all gazes, anisocoria, and visual impairment implied orbital apex compression. Computed tomography showed several distinct lesions with mild delayed enhancement extending to the orbital apex. Through a lateral orbitotomy, 10 discrete hemangiomas were removed uneventfully. Histopathologic findings were consistent with cavernous hemangioma in all tumors removed. Proptosis resolved after surgery at 3 to 4 weeks. Visual acuity was unchanged (20/25), and eye movement significantly improved at last follow-up, 15 months after surgery.
