Changes to upper eyelid orbital fat from use of topical bimatoprost, travoprost, and latanoprost.
    Japanese journal of ophthalmology, 2011, Volume: 55, Issue:1

    To confirm the possible mechanism by which topical prostaglandin antiglaucoma drugs cause a deep superior sulcus.. Among patients who used bimatoprost (Lumigan), latanoprost (Xalatan), or travoprost (Travatan) and who developed a deep upper lid sulcus, 18 eyes of 11 patients (mean age, 58.2 ± 8.9 years) were studied. Seven patients were binocular users of one of the eye drops and four were monocular users. Preaponeurotic orbital fat was obtained, and the mean adipocyte density compared.. In the four monocular users, mean adipocyte density of treated eyes was 1758.21 ± 158.15 cells/mm(2), and that of untreated eyes was 1258.73 ± 127.54 cells/mm(2). This difference was statistically significant (P = 0.04), suggesting that the adipocytes were atrophied in the treated eyes. The mean adipocyte density of the bimatoprost group was 2073.35 ± 184.89 cells/mm(2), that of the travoprost group was 1623.46 ± 218.99 cells/mm(2), and that of the latanoprost group was 1468.20 ± 113.44 cells/mm(2). The densities of the bimatoprost and travoprost groups, but not of the latanoprost group (P = 0.75), were significantly different from that of the untreated group (P < 0.001).. Fat atrophy can be considered a mechanism of upper eyelid sulcus deepening in patients using topical prostaglandin analogs.

Periorbital fat atrophy - an unfamiliar side effect of prostaglandin analogues.
    Orbit (Amsterdam, Netherlands), 2010, Volume: 29, Issue:6

    Prostaglandin F2 alpha (PGF2a) analogues including bimatoprost and travoprost are used worldwide, often as first line topical treatments for glaucoma. We present 2 cases of a newly described side effect of both these topical agents in terms of periorbital fat atrophy. This visually noticeable side effect had features demonstrable on MRI scanning. The periorbital fat atrophy is most apparent with uniocular use and both doctors and patients need to be aware of this side effect before commencing treatment. The effects, however, appear to be reversible with treatment cessation.

[Orbital fat atrophy in glaucoma patients treated with topical bimatoprost--can bimatoprost cause enophthalmos?].
    Klinische Monatsblatter fur Augenheilkunde, 2008, Volume: 225, Issue:5

    The aim of this communication is to report enophthalmos as a possible new adverse effect of topical bimatoprost treatment.. A retrospective case series of five glaucoma patients under long-term topical bimatoprost treatment was evaluated. Documentation with photo and Hertel exophthalmometry was reviewed.. In all five patients a deep lid sulcus, reduced infraocular fat pads and enophthalmos-suspicious Hertel values were found (mean 11.9 mm; SD 2.4). Other aetiologies for enophthalmos were excluded anamnestically and by clinical examination.. Bimatoprost may lead to an alteration of the eyelid with deepening of the lid sulcus and may also be responsible for an iatrogenic orbital fat atrophy. A possible mechanism of action might be the induction of apoptosis of orbital fibroblasts with a remodelling of the extracellular matrix. Prospective studies are necessary to confirm this cross-sectional observation.
