Intermittent exotropia (IXT) is known to relapse after surgery. No factors to predict or prevent recurrence are known with certainty. This study investigated surgical outcome, potential influencing factors, and reoperation rate in patients with IXT.

The aim of this study was to evaluate retinal and optic nerve head (ONH) perfusion in patients with inactive Graves ophthalmopathy (GO) and compare it to healthy controls using optical coherence tomography angiography (OCTA). Twenty-nine eyes of 29 patients with inactive GO (study group) and 29 eyes of 29 healthy subjects (control group) were included in this study. The vessel density (VD) data in the superficial and deep retinal OCT angiogram of the macula and the radial peripapillary capillary network (RPC) were extracted and analyzed.

Background/aims: To analyse the distribution of macular ganglion cell layer thickness (GCLT) in patients with foveal hypoplasia (FH) with or without albinism to obtain new insights into visual pathway anomalies in albinos.

Methods: Patients with FH who presented at our institution between 2013 and 2018 were retrospectively drawn for analysis. Mean GCLT was calculated after automated segmentation of spectral domain-optical coherence tomography (SD-OCT) scans.

Background: Tumors of the lacrimal sac are a rare entity. Malignancies are often associated with a high mortality rate. Lacrimal sac tumors often present as lacrimal duct stenosis with dacryocystitis and are often only diagnosed after an intraoperative biopsy.

Purpose: Cryotherapy as a destructive procedure is an important alternative to the surgical excision of eyelid tumors.

Methods: We report our own experiences in the cryotherapy of large upper eyelid papillomas using spray- and contact-freezing.

Results/conclusions: Cryotherapy gave excellent results in the treatment of unusually large papillomas.

Adenoid cystic carcinoma of the lacrimal gland (ACC) is a rare malignant orbital tumour with a poor overall prognosis. Current therapeutic approaches like radical and local surgery, adjuvant radiation and neoadjuvant intra-arterial chemotherapy are controversial. We present three cases of patients with ACC with different therapy concepts and discuss these with current recommendations from the literature.

Background: Systemic autoinflammatory diseases (SAIDs) represent a growing number of monogenic, polygenic or multifactorial disorders that are often difficult to diagnose.

Case Presentation: Here we report a patient who was initially erroneously diagnosed and treated for SAID. Symptoms consisted of recurrent fever, erythematous and/or blistering skin lesions, angioedema, susceptibility to bleeding, external ear infections and reversible anisocoria in the absence of laboratory evidence of systemic inflammation.

Background: Reliable measurement of intraocular pressure (IOP) is crucial in pediatric patients with suspected glaucoma. General anesthesia (GA) is usually needed in infants to allow a thorough examination. However, anesthesia itself may influence IOP, depending on the type used and the depth of sedation.

Purpose: Leukemic hypopyon uveitis in acute myeloid leukemia (AML) is a very rare condition. We report this case of an unusual finding in a 2½-year-old boy in second remission after chemotherapy for relapsed AML.

Methods: A young patient with an AML FAB M5 in second remission developed pain, photophobia, and conjunctival injections in the right eye.

Conclusions: The transconjunctival approach to orbital floor fractures permits excellent exposure of the inferior orbit and provides a good surgical outcome, especially with regard to ocular motility.

Objective: Surgical access to orbital floor fractures can be accomplished via the transconjunctival approach. The majority of studies on this subject deal with surgical aspects and complications.

Introduction: Over the last decades, various methods have been investigated for preschool screening for amblyogenic ametropia. The SureSight is a new hand-held wavefront-analyzing autorefractor designed for screening.

Methods: A total of 338 children (3 1/2 - 4 1/2 years-old) were examined in their kindergartens without cycloplegia using the new instrument.

Background: The role of the lacrimal sac (LS) and the medial canthal tendon in the lacrimal pump mechanism is controversial. This study used ultrasonic visualization to analyze this phenomenon.

Methods: Movements of the LS and the medial canthal tendon during blinking were visualized with sonography.

Introduction: Permanent visual damage due to an increase in volume of the orbital contents may be the result of the failure of conservative therapeutic concepts in the treatment of endocrine orbitopathy. Considerable progress has been achieved in developing successful orbital decompression techniques with regard to functional and cosmetic outcome. Decompression techniques with resection of the bony orbital walls are adequate tools in restoring visual acuity and reducing exophthalmus.
