Purpose: Dermatofibromas are common cutaneous lesions, but rarely occur in the eyelid skin. The reason for the low incidence in the palpebral skin has not been elucidated. In this study, we analyze the histopathologic features of an illustrative case of dermatofibroma and review previously published cases to determine whether eyelid dermatofibroma develops differently from the prototypical dermatofibroma.
Methods: Histopathologic analysis of a new illustrative case of eyelid dermatofibroma and retrospective review of published cases.
Results: The distinguishing features of the illustrative lesion included a rounder gross appearance, nonacanthotic epithelium, basophilic staining, cellular character, and a paucity of "collagen trapping." These features deviated from the typical features associated with classic dermatofibroma. Review of the 11 previously published cases of eyelid dermatofibroma revealed that they were more similar in appearance to the illustrative lesion than to classic dermatofibroma.
Discussion: The rarity and histological deviations of the eyelid dermatofibroma suggest that the dermal substrate from which the lesion develops differs from that of the classic dermatofibroma. This difference may be explained microanatomically based on the fact that the dermis of the eyelid is predominantly papillary, whereas the dermis of extrapalpebral skin where dermatofibromas are more common is predominantly reticular.
Conclusions: Although related, eyelid dermatofibromas appear to be histologically distinct from classic dermatofibromas, owing to the unique dermal composition of the site of origin.

Purpose: This study evaluates the reliability of a frequently used subjective measurement of orbital compliance (0-3 scale) and describes a simple, quantitative measure with excellent intra- and interrater reliability.
Methods: Two examiners performed both measurements on 100 orbits (50 consecutive patients) from the office of 1 oculoplastics surgeon. Each measurement was obtained at 2 different time points, 10 minutes apart. For the subjective measurement, the patient was asked to close their eyes, and the globe was displaced posteriorly with digital pressure until moderate resistance was felt. This was graded on a 0 to 3 scale. For the quantitative measurement (millimeter scale), the difference in axial displacement was measured using a Hertel exophthalmometer.
Results: The subjective measurement (scale, 0-3) showed excellent test-retest reliability (average, 0.901) for both examiners at both time points and good interobserver reliability (average, 0.677). The quantitative measurement (millimeter scale) showed excellent test-retest reliability (average, 0.848) and very good interobserver reliability (average, 0.756).
Conclusion: This study shows that while both methods have both excellent test-retest reliability, the interobserver reliability is slightly higher with the quantitative measurement. This suggests that the described measurement of orbital compliance is both a reasonable alternative and possibly more accurate measurement without the steep learning curve.

Purpose: To evaluate the aesthetic and functional outcomes of autologous fat transfer using the SEFFI (superficial enhanced fluid fat injection) technique for reconstruction of the periocular area.
Methods: Autologous fat injections prepared with the 0.5 mL and 0.8 mL SEFFI technique were used in four patients for periocular rehabilitation.
Results: Case 1 (C1): A patient with left-sided progressive facial hemiatrophy underwent ipsilateral volumizing with 0.8 SEFFI in the superior, temporal, and inferior periorbital areas, and 0.5 SEFFI in both eyelids. C2: A 21-year-old female with a post trauma frontal scar, left ptosis, and lower eyelid retraction was treated with 0.5 SEFFI applied in the scar area associated with an upper eyelid conjunctivomullerectomy and resection of the lower eyelid retractors. C3: A patient with previous left-eye evisceration and orbital floor and medial wall fractures underwent socket reconstruction with buccal mucosal graft in the lower fornix and 0.5 SEFFI injections in both superior and inferior eyelids. SEFFI was also applied in the intraorbital space for correction of the enophthalmos. C4: A patient with lower lid retraction post blepharoplasty was treated with 0.8 SEFFI injections in lower eyelids and malar areas, complemented with a bilateral lateral cantopexy.
Conclusions: Autologous fat transfer with SEFFI technique is an effective and safe procedure in cases of periocular rehabilitation.

Horner's Syndrome (HS) is a neurological syndrome characterised by the triad incomplete pupillary miosis, palpebral ptosis and facial anhidrosis, due to a lesion of the oculosympathetic pathway, formed of three neurons from the hipothalamus to the eye. Identifying its cause is a diagnostic challenge since in spite of its apparent lack of clinical importance, HS can be the first or only manifestation of a serious, or even potentially mortal disorder. We present the case of a 19-year-old male patient with a history of nonspecific ocular pains of two months evolution. He attended the emergency ophthalmological clinic where he was diagnosed with an HS as the first clinical manifestation of Hodgkin lymphoma.

OBJECTIVE: To present the case of a patient with a posterior microphthalmos-optic disc drusen-retinitis pigmentosa syndrome associated, for the first time, with white dots in the posterior pole.
METHODOLOGY: The posterior microphthalmos, retinitis pigmentosa and optic disc drusen syndrome was described for the first time in literature in 1991. Later, it was associated with a pattern of foveal thickening and/or foveoschisis. Different forms of mutations on chromosomes 11 and 14 have been identified as being responsible for the appearance of this syndrome, but the inheritance pattern is unknown.
DISCUSSION: The case is reported of a 37 year-old man, with no personal or family history of interest, diagnosed with this syndrome in association with white dots in the posterior pole. Such a morphological association has never been published before in literature.
CONCLUSION: The posterior microphthalmos, retinitis pigmentosa and optic disc drusen syndrome is a very rare entity, and has never been described associated with white dots in the posterior pole. More case reports are needed to establish clear patterns of both the disease and inheritance.

Cyclodialysis is the result of the separation of the longitudinal fibres of the ciliary muscle from their sclera insertion, creating states of ocular hypotony. It is mainly caused by traumatisms. Gonioscopy has traditionally been the diagnostic test for this entity, however, at present it is being replaced by other techniques, such as ultrasound biomicroscopy (UBM). We present the case of a 57-year-old male who, following a traumatism in the left eye caused by the disc of a radial saw, presented corneal perforation and vitreous haemorrhage with pan-retinal edema. The gonioscopy was normal in spite of the existence of persistent ocular hypotony. The realization of a UBM enabled diagnosis of a small cyclodialysis of less than ten degrees. Surgical treatment made it possible to recover normal intraocular pressure.
