Dermoid cysts are epidermis-like cysts with dermal adnexal structures such as sebaceous glands, hair follicles, or sweat glands in the cyst wall. They contain mature or immature germ cells of pluripotent origin. The usual sites of occurrence in the periorbital region include the lateral angle of the orbit, medial angle, limbal, and deep orbital region. Here, we present a case of 16-year-old female who came to the hospital with complaints of swelling in the upper eyelid and intermittent pain. After an excisional biopsy of the mass was done, the diagnosis of tarsal dermoid cyst was confirmed. Due to the paucity of cases in literature, reporting this case may help shed light on the importance of including dermoid cyst in the differential diagnosis of a tarsus-based eyelid mass.

Objective: The objective of this study was to assess the incidence of complications intra- and postoperative (until the 30^th day) of phacoemulsification surgery performed by residents of the third year, and its implications on final refraction and best-corrected visual acuity (VA), compared to those who did not exhibit any complication. Methods: This was a retrospective analysis of 300 medical records of patients who had their surgeries performed from January 2019 to February 2020 by the same three third-year residents. Fifty medical records were excluded. Initial VA logarithm of the minimum resolution angle and final VA with the best correction were analyzed, comparing whether there was a correlation with the presence of complications. Results: Of the 250 medical records analyzed, 29 (11.6%) presented complications during the intraoperative period, been posterior capsule rupture the mean one. The mean VA of patients without complications was 0.13 ± 0.17 (0.00–1.00) compared to 0.29 ± 0.28 (0.00–1.00) for those who had complications. The spherical equivalent of those without complications was −0.87 ± 0.98 (−4.38–2.00) compared to −1.19 ± 1.14 (−3.75–0.50) of the that had. Conclusion: As shown in this study, the percentage of complications is compatible with those found in the literature, also exhibits that surgeries with complications do imply in worst VA. However, when compared among themselves, before and after surgery, there was a significant improvement in the VA even in patients with complications.

Cytomegalovirus (CMV) is a double-stranded DNA virus. It is an opportunistic infection that usually affects individuals with AIDS or with profound immunosuppression. CMV retinitis is the most frequent ocular manifestation. Infrequently, this pathology has been observed in patients undergoing immunosuppressive treatment due to autoimmune diseases. This article presents a case of Crohn's disease with systemic and ocular involvement by CMV after starting treatment with infliximab (anti-tumor necrosis factor-alpha antibody).
